Meet Svulp Rechargeable Heated Insoles, a high-performance thermal insert designed to deliver steady warmth in cold environments. Featuring a compact 8W heating circuit, these insoles provide immediate plantar warmth and are optimized for use in industrial work boots, outdoor footwear, and everyday trainers. Dual-zone heating ensures heat is distributed evenly across the metatarsal and arch regions, supporting improved peripheral circulation in sub-zero temperatures. The insoles use a high-density EVA construction, delivering structural support, breathability, moisture resistance, and odor control. Custom sizing is made simple with precise cutting guides, allowing you to trim the material for an exact fit within EU sizes 35–40 or 41–46. The system operates via a USB power protocol of 5V/2A, making it compatible with portable power banks and standard USB wall adapters for either continuous or intermittent heating cycles.
